Subject: [PATCH 0/4] MMCC MSM8998 fixes

8998 has a couple of issues related to its clock controllers. This series
attemps to fix some of them.

The DT patch should go in first for bisectability, otherwise
clk/pd_ignore_unused will need to be used, as the SMMU GDSC is no longer
considered always-on.

This series results in less "clk stuck at 'on/off'" messages and should
marginally reduce power consumption.
